Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention is a watertight, airtight seal that is affixed to the outside of the abutting part of a heat insulating plate stretched to insulate a building floor, wall, roof, etc. The present invention relates to a joint tape for a heat insulating plate, which has excellent heat resistance, water resistance and heat insulating properties.

Technical background of the invention In order to enhance the heat insulation performance of buildings such as houses, insulation materials are applied to walls and roofs. Although glass wool and the like are known as heat insulating materials, glass wool has a problem in that it absorbs water and has durability, and since it is not easy to construct, heat insulating plates made of expanded polystyrene or the like have recently been used. Has become. An example of constructing a wall heat insulating structure using such a heat insulating plate is shown in FIG.

As shown in FIG. 7, a heat insulating plate 3 is stretched in the surface direction on the outdoor side of the pillar 1 and the stud 2, and the furring strip 4 is brought into contact with the outside thereof. The heat insulating plate 3 is fixed by nailing in the direction, and the desired heat insulating performance is obtained by the heat insulating plate 3.

In FIG. 7, reference numeral “6” indicates an interior material and “7” indicates an exterior material.

In such a conventional heat insulating structure, a gap is likely to be formed in the abutting portion 12 between the heat insulating plates 3, and the airtightness and the heat insulating property may be deteriorated in this portion. In order to improve the airtightness, a sealing material is filled so as to close the gap m between the abutting portions 12 between the heat insulating plates 3, or an airtight tape is applied to the abutting portions 12 of the heat insulating material. Since the work of filling the sealing material is complicated, it is recommended to use an airtight tape.

However, since the conventional airtight tape is a kraft paper coated with an adhesive, there is no problem in terms of airtightness, but watertightness, waterproofness and heat insulation, in particular, poor heat insulation,
Even if the heat insulating plate is stretched, if the heat insulating property is lowered at the abutting portion of the heat insulating plate, there is a disadvantage that the heat insulating efficiency is poor.

The purpose of the present invention is to eliminate the disadvantages of the above-described conventional technology, and the abutting part of the heat insulating plates that is stretched to insulate the floor, wall, roof, etc. of the building It is an object of the present invention to provide a joint tape for a heat insulating plate, which is adhered to and is excellent in watertightness, airtightness, waterproofness and heat insulation.

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention closes a gap formed at a butt portion of a heat insulating plate that is formed by stretching a heat insulating plate in the surface direction on the outdoor side of a columnar body such as a pillar, a stud, or a rafter. As described above, the joint tape of the heat insulating plate adhered to the outdoor side of the abutting part of the heat insulating plate, wherein the joint tape is a base tape made of soft vinyl chloride having independent air bubbles, and the base tape And a pressure-sensitive adhesive layer provided on one surface, wherein the pressure-sensitive adhesive layer of the joint tape is attached to the outside of the abutting portion of the heat insulating plates so as to close the gap between the heat insulating plates. It is characterized by comprising a soft vinyl chloride foam.

The joint tape according to the present invention comprises a base tape made of foamed soft vinyl chloride having closed cells, and an adhesive layer provided on one surface of the base tape.

Therefore, the joint tape of the present invention is excellent in watertightness, airtightness, waterproofness and heat insulation property, and when the joint tape closes the gap between the abutting ends of the heat insulating plates, the watertightness and airtightness at the abutting portion. And water resistance and heat insulation are improved, and especially the heat insulation of the entire wall is also improved.

Detailed Description of the Invention Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 is a perspective view of a main portion of a joint tape of a heat insulating plate according to an embodiment of the present invention, and FIGS. 2 and 3 are cross-sectional views and perspective views of a main portion showing a tension structure of a heat insulating plate using the joint tape. 4 and 5 are cross-sectional views of the main part showing the tensioning structure of a two-layer heat insulating plate using the same joint tape, and FIG. 6 is a diagram showing the tensioning structure of the heat insulating plate in the roof using the same joint tape. It is a partial perspective view, and the members common to the members shown in FIG. 7 are denoted by the same reference numerals.

A joint tape 11 of a heat insulating plate according to an embodiment of the present invention shown in FIG. 1 is composed of a soft vinyl chloride foam having closed cells and an adhesive feed, that is, one of the soft vinyl chloride foam foam tapes. A sticky agent layer is formed on the surface, and the joint tape and the heat insulating material of the present invention are bonded by this adhesive. Further, the joint tape 11 on the side coated with the adhesive may be covered with the release paper 12. This is to improve the workability of the joint tape.

Since the joint tape 11 is made of soft vinyl chloride having closed cells, it is excellent in watertightness, airtightness, waterproofness and heat insulation. The wall thickness of the joint tape 11 is preferably 0.5 to 2 mm. The tape-shaped soft vinyl chloride is produced by a known means.

As an adhesive applied to such a joint tape,
Acrylic, acrylic modified urethane, etc. are used.

 A construction example of such a joint tape is shown below.

As shown in FIGS. 2 and 3, an interior material 6 is stretched on the indoor side of a building in which a pillar 1 and a stud 2 are vertically installed.
In this embodiment, a single layer of heat insulating plate 3 is stretched around the outdoor side.

An inner ventilation layer 10 is formed between the heat insulating plate 3 and the interior material 6.

Since this heat insulating plate 3 has a predetermined size and is stretched in the surface direction, each heat insulating plate 3 has a gap m (which is exaggerated and shown broadly in the drawing) in the butted portion 12. ing.

In this embodiment, the joint tape 11 is attached to the outside of the abutting portion 12 of the heat insulating plate 3. Then, the furring strips 4, 4 are struck from above the joint tape to the pillars 1 and the studs 2, and the exterior material 7 is attached to the outer side of the furring strips 4, 4. The joint tape 11 does not necessarily have to be provided at a position corresponding to the furring strip 4, but the joints 12 of all the heat insulating plates 12
It is preferable to stick it to.

The heat insulating plate 3 is preferably a synthetic resin foamed heat insulating plate, and is a foamed plate having a closed cell structure which is made by foaming a synthetic resin such as polystyrene, polyethylene, polyvinyl chloride, or polyurethane 5 to 50 times, and has a thickness of 20. It is preferably about 100 mm. Above all, it is effective to use an extruded polystyrene foam plate having a high degree of rigidity, heat insulation and moisture resistance.

Next, a method of constructing a heat insulating wall using such a joint tape will be described.

First, the inner heat insulating plate 3 is stretched in the surface direction on the outdoor side of the pillar 1 and the stud 2. As a result, an air layer 10 is formed between the pillar 1 and the stud 2.

Next, the joint tape 11 is attached to the outside of the heat insulating plate 3 so as to close the gap m between the butted portions 12 of the inner heat insulating plate 3.

Then, the furring strips 4, 4 are attached from above, and the exterior material 7 may be mounted on the outside of the furring strips 4, 4 and the interior material 6 may be mounted on the interior side of the pillar 1 and the stud 2.

With the heat insulation wall molded in this way, the joint tape 11
Has excellent watertightness, airtightness, waterproofness, and heat insulation, so that the watertightness of the abutting portions 12 of the heat insulating plates 3 with each other,
Airtightness, waterproofness and heat insulation are improved, and especially the heat insulation of the entire wall is also improved.

The present invention is not limited to the above-described embodiment, and can be variously modified.

For example, as shown in FIGS. 4 and 5, the heat insulating plate has two layers of an inner heat insulating plate 3 and an outer heat insulating plate 5, and a joint tape 11 is attached to the outer side of the inner heat insulating plate 3 and the outdoor side thereof. Further, the outer heat insulating plate 5 is stretched so that the butting portion 12 or the butting portion 12a with the furring strip 4 does not overlap with that of the inner heat insulating plate 3.

In the stretched structure of the heat insulating plate formed in this way, since the joint tape 11 is attached to the outdoor side of the inner heat insulating plate 3, the gap m ₁ between the inner heat insulating plate 3 and the gap m between the outer heat insulating plate 5 is _This will cut off the communication between the _two , effectively preventing the leakage of indoor air and the ingress of outside air, and further improving the thermal insulation performance of the room.

If the joint tape 11 is adhered to close the gap m ₁ , the butt end 5a of the outer heat insulating plate 5 does not need to be tightly adhered, and the outer heat insulating plate 5 can be easily and quickly attached. Can be done This is because the joint tape 11 blocks the air flow path. Also,
When the joint tape 11 is attached to the outside of the inner heat insulating plate 3, the joint tape 11 is pressed by the outer heat insulating plate 5, so that there is no risk of peeling.

Further, the present invention can be applied not only to the wall structure but also to the roof structure as shown in FIG.

In the example shown in FIG. 6, a plate material 21 and the like are provided on the outdoor side of the rafter 20 and two layers of heat insulating plates 3 and 5 are stretched on the outdoor side of the plate material 21. The joint tape 11 is provided on the outdoor side of. And the outer heat insulating plate 5
